I have an application than disables the screen saver temporarily in order to run a slide show. I use this to turn it on or off:
i = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, active, Nothing, SPIF_SENDWININICHANGE)
This works fine in XP. In Windows 7, it disables the screen saver properly. However, when it is enabled again, at the normal time for the screen saver to come on, the system asks for a password instead of showing the screen saver.From this time on until the screen saver settings are adjusted in the control panel, the password screen is displayed in place of the screen saver.Is there something else I should be doing for Windows 7? I understand that SPI_GETSCREENSAVEACTIVE is not supported in Windows 7, but SPI_SETSCREENSAVEACTIVE is supposed to be.

We are running XP workstations in an Active Directory domain. I used gpedit.msc to setup a startup script that launchs Spy++. This works, and just before the login screen comes up, Spy++ pops up. The only problem is, the Spy++ window then goes away just before the login window loads.
I want to use Spy++ to find the attributes of the XP (Active Directory) login window. Is there a way to do this?

View 3 RepliesHow do i run my current screen saver from VB2008 on the click event of a command button in my form?
View 1 RepliesOur program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.

After running the following code (which locks the computer), what code must I be applying to see if the user has successfully logged into the computer and that "Lock Screen" I'd so called has disappeared?
Private Declare Function LockWorkStation Lib "user32.dll" () As Long
Private Function LockComputer()
LockWorkStation()
End Function
I will call "LockComputer", after that what do I do to see if the Lock screen so called by this function (after say 2 minutes) has disappeared or is still there asking for the password from the user.

View 2 RepliesIn Windows Vista/7/2008/2008R2, is it at all possible to launch a process in a user's session from a service?

View 3 RepliesWe have a company intranet and the powers that be think it would be nice to have a collection of icons/links representing the applications that most reps use (Outlook, Excel, few other apps).
The idea would be that if the application is installed, clicking the link/icon would launch the application on the client machine.
Anyone ever had a requirement like that and been successful implementing it?
The problem is as follows: If Windows starts up in Safe Mode, no applications I make with VS 2010 will run. Even if I try to launch them, doubleclicking, running, almost everything I tried, the problem is that the application just doesn't show up. There is no window there, and I don't know (haven't checked) if a process related to the application is running.

I run the app under current logged in user from the service.To give you background, I have a VB.NET Windows service whose sole functionality is to run a Winform App at a specified time. Apart from that it also sets a system wakeup timer so that the system can be woken up at the specified time, if it goes into standby/sleep, to run the app. This service has to cater to XP/Vista/Win7 desktops on our network. This service won't run on servers and laptops.
The Winform App shows a UI for the user to provide some inputs. If the user does not provide the input within 15 minutes, then it defaults the value and then goes into system tray icon. The user can click on the icon and change the values later (within in a specified time frame and that too only twice).
There is absolutely no interaction between the service and the winform app apart from the service starting the app. It also monitors if the app has been killed by the user/crashed. If it has been killed/crashed, then a new instance is run after 30 mins from previous run.
If there is no user logged on, then also I want the app to be run at the specified time. As I said before, the app has a default timer. So if some user has just logged off from the system, then defaults would be set by the winform app.Now coming to why I am stuck with this design - I cannot use TaskScheduler because it has been disabled on all machines and security team is not willing to change it. TaskScheduler had the option to wakeup the machine from sleep and other things. So basically I ended up creating a service which is acting like task scheduler.
Currently when I run the app.exe via process.start() within the service, its running under SYSTEM account as the service is also running under LOCAL SYSTEM. So basically I am not getting any UI. Is there anyway to run it under the current logged in user? I am not worried about multiple user login as we wont be running it on servers and switch user is not enabled on our desktops. Even if somebody has done a remote login via mstsc, then also I need the run the app and show the UI to the user.
I have seen various applications that can be launched from a link embedded in a web page. example: irc ://irc .freenode.net/#roomname Opens IRC and joins the room.
View 1 RepliesI am running Microsoft Visual Basic 2010 Express. I created a simple program that is nothing more than dozens of Windows Forms that are linked together by the various clickable buttons I put on each form. The program is like a "book" with several pages, and you jump to a specific page by clicking on specific buttons on the current page ("Windows Form").
My question is, how do I change my program so that when it is launched, instead of just 1 Windows Form opening, the program opens up several Windows Forms (of my choosing) automatically? In other words, instead of my "book" (VB program) opening "page 1," when I run it, I want it so that pages 4, 7, 8, 10, and 15, are "opened" whenever I run my "book."
Is there some code I need to insert into each Windows Form I wanted opened automatically when the program is loaded? Or is this a MS VB 2010 Express environment option I need to set?
I can launch Excel with the document I want using VB.Net 2010:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.xlsx"
p.Start()
Excel starts OK with the file opened. I edit the file, but when I close it down, Excel doesn't ask if I want to save changes. So it closes and loses my edits.
If I do the same with a text file:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.txt"
p.Start()
It opens (in Notepad++), I edit it and close it, and Notepad++ asks if I want to save changes.
I've now tried similar code with a Word document - and that's OK. Also with an OpenOffice Sheet document and that works as well.
This behaviour is happening in Windows 7 with Excel 2010. It works as expected in Windows XP with Excel 2007.
What am I doing wrong with Excel? Is it me?
